RULING-MACHINE.

SPFCATION forming part of Letters Patent No. 258,642, dated May 30, 18 82. y

Application filed February 7, 1882.

To all whom it may concern:

Be it known that I, SIDNEY A. GRANT, a citizen of the United States, residing' at Springfield, in the county of Hainpden and State oi' Massachusetts, have iuvented new and nseful Improvements in Vertical Oomponnd Ruling- Machines, of which the following is a specification.

This invention relates to iinprovements in ruling-machines provided with duplicate sets of ruling-pens, the object being to provide improved devices for ruling a continuous strip of paper upon both sides thereof by once passing it through the machine, and to provide improved mechauism for so unrolling the paper from a roll that it may freely be drawn under the rnling-pens irrespective of the Weight of said roll.

In the drawings forming part of this specification, Figure 1 is an elevation of a rulingmachine constrncted according to my invention. Fig. 2 is a side elevation ofthe rollers, paper tensions and gnides, and pen-supporting devices ofthemachine,with the frame thereof removed,vshowing the manner of conducting the strip of paper from its roll through the machine.

In the drawings, A is the frame of the inachinc. B represents the roll and the strip of paper drawn therefroln. c c' are gage and tension-snpporting rods. 'v c c are gage-hlocks adjustahle on rods c c'. e' is a tcnsion-spring support. e is a tension-sprin. 0 0 are papercarrying rollers. a n n n are pressnre-rolls. ca are pen-supporting devices. i indicates rnling-pens. mare pressnre-blocks, and 00' are pressurescrews.

Like letters refer to like parts in the different figures.

The machine hcrein dcscrihed provides siniple and efficient means for ruling a strip of paper to form thercon series ofparallellines from end to end of said strip, and upon hoth sides thereof, by once passing said paper through said machine, and provides novel means for drawing the paper to be so rnled from a roll ihereof of considerable size and Weight, but without any tensile strain upon that part of said strip which is passing over the papcrgnides and under the rnlingdevices which can interfere with its regular and nniform move- (No model.)

and each of said blocks having a pressurescrew, x', set in said frame directly over it, and adapted to be screwed down upon said block. Upon each ofsaid shafts, which are hnng under said blocks, are two rolls, n a, whose peripheries bear upon the surface of said rollers 0 o with more or less force, accordin g to the adj nstment of said screws and pressure-blocks.

The pen-supporting devices and pens represented by the letters a and z' may be of any of the ordinarydescriptions, and are supported upon proper brackets in such a position that the pens 2' may rest upon said rollers 0 \0 as shown, one set of pens upon each roller, and each set upon opposite sides of the machine.

Upon braokets proj ectin g from opposite sides of frame A are sccured the gage and tension snpporting rods c c' in pairs-two on each side of the machine Upon each pair of said rods are placed two ga ge or guide blocks, c, adapted 'to be moved thercon and set to certain positions by proper set-screws in them, as shown. Upon each of said rods cis provided a tensionspring support, e', so secnred thereto as to be moved horizontally upon said rods or turned thereupon, and arranged to be set by a snitahle screw to the desired position on said rods. On each of said supports e' is fixed atensionspring, e, adapted to bear against the rod c'.

The operation of my machine is as follows: The end of the strip of paper from the roll B is carried first back of the lower pair of rods c o', and over rollcr o, between the face of' the latter and the peripheries oi' the pressure-rolls n a, and thence down under said roll B, and is made to hang loosely under the latter, as shown, the end of said strip being now carried up between the lower pair of rods c c', and between the tension-spring e and said rod IOO c', and thence again between roller 0 and the rolls n n, which run upon its surface, and lying upon that part of said strip of paper which was first carried over said roll 0, as aforesaid. The said paper strip is now allowed to hang down in a loop shape below roll 0, as shown in Fig. 2, and then carried between the upper pair of rods c c' upon the left-hand side of the machine and under the tension-spring e, as aforesaid, and theuce between the face ot' roll 0 and the peripheries of the rollers n n hearing thereupou, and thence the paper passes to any convenient roll, upon which it is wound, or to the usual eutters, by which it is cntinto sheets. and roll 0 as at'oresaid, it passes under the ruling-pens z', of the usual Construction, and as it passes over the roll o it is ruled ou one side and upon the opposite side, as it passes over the upper roll, 0

The gage or guide hlocks v on rods c c' are set on said rods according to the width of the strip of papel, and serve to keep the paper in a proper line of movement under the rulingpene and over the rollsoo. Thetenson-springs e e serve to keep the paper strip straight as it goes under the pens byofering a slight resistance to the paper as it passes along. The effect of the pressure of rolls nnupou the under line ot' said paper strip, which is first carried over roll 0, is to cause the paper to draw with a steady motion off from roll B and to cause the tensile stra-in upon said strip, which the rotation of roll B causcs,to be thrown entirely upon that part of the paper which first passes from said roll B between the fice of roll 0 and the rolls n n. Thus the overlapping portion of the paper strip which ruas outside of the first one and between the rods c c' and under the peus i is so freed from all tcnsile straiu that it can be drawn with ease and regularity thereunder, and good ruling be done. The paper strip, after having passed by roll 0, is al- As the paper strip passes over roll 0 lowed to freely hang down, as shown, to give its first-ruled side time to dry and to give ita free and easy movement toward the upper and second set of ruling devices. The passage of two superposed strips of paper between roll o and the rolls n n bearing thereon causes no inconvenience; but roll B is steadily turned and the upper strip moves steadily and with a uniforin motion while being ruled, as does also that part of the strip which runs singly between roll 0 and under rolls n n.

It is obvious that ruling upon one side of the papel' strip can be conveniently accomplished by passing said strip only under the lower line of pens i and over roll 0.

What I claim as my inveution is 1. lu a machine for ruling two sides ofa strip of paper simultaneously, the combination, with two sets of ruling devices, of the rolls 00 and adjustable pressure-rollers n n to revolve and bear upon thc paper as it passes between said rolls 0 o and said rollers n n, substautially as set forth. V

2. In a papenruling machine, the combination oftwo pairs ofrods,cc', two tension-springs, e, two sets of suitablc ruling devices, the rolls 0 0 and two pressure-rollers,nn, to hear upon each of said rollso o substantially as set forth.

3. The withiu-deseribed improvementin the mcthod of feeding a strp of paper from a roll, B, thereo' to the ruling devices of apaper-ruling, machine, which consists iu seizing the end of said strip which leads directly from said roll between revolving pressure-rollers, then passing said end loosely around said roll, then between a suitable tension device and under ruling devices, and again between said revolving pressurerollers, substantially as set forlh.
